Hi, I recently brought a brand new MSI Radeon RX 480 Gaming X 4GB, however when i install it into my system, the PC simply will not start, no sign of power, no boot, no lights, nothing.

However when i disconnect the PCI-E power cable to the GPU and start the PC, the PC will boot fine, even the RX 480 will light up, but no signal on display, only able to use on board graphics.

My Old GPU was a Gainsward G1 GTX960, which works fine with the system.

Here are my system Specs:
CPU: i5 6600
MOBO: GIGABYTE H170M - D3H
RAM: 16GB G.Skill ripjaws 2 * 8gb
PSU: Corsair CX550M (grey label not green)
SYSTEM: Windows 7

I have also flashed BIOS to the most recent edition from gigabyte (F21).

Any and all help is very much so appreciated, thanks

Hi,
I am having a similar problem with the MSI RX 480 8 GB.
My system has:
i7 4790
8 GB DDR3
MSI z97 Gamming 7
EVGA 600W.

The motherboard I got about 3 weeks ago and the GPU yesterday. The PSU is also quite new - 4 months old.

I plugged in the GPU turned the pc on and it was ok. I then inserted the cd that came with GPU and started download the utilities when the screen went black.
Since then, I reinstalled windows 10 (64), and most of the time I can't go further then the boot screen before all goes black. In safe mode the screen takes longer to go black but by the time everything opens up it ends up dead.
I tried 2 different PCI slots on the motherboard with the same results.
Reading online I played with the settings in bios...

Reading online I played with the settings in bios legacy/ uefi but no success.

the monitor i'm using is a 49inch LG UHDTV with a hdmi 2.0 cable connected to gpu. I tried with a different hdmi cable and no difference.

Any help would be appreciated.
Thank you.

An important question - when you first plugged your GPU you and turned the TV on and it worked, was your HDMI cable plugged into the motherboard's HDMI socket, or the GPU's socket?

And have you updated the BIOS for the motherboard? This is what worked for me in the end. Sounds like a silly question but the motherboard you bought 3 weeks ago may we have been designed a few years ago ?
